Error:
The provider could not determine the Double value. For example, the row was just created, the default for the Double column was not available, and the consumer had not yet set a new Double value.
If you encounter this error message "The provider could not determine the double value. For example, the row was just created, the default for the double column was not available, and the consumer had not yet set a new double value" during the installation of Webgility, it may be due to a permissions issue preventing the latest installer from replacing old files in the installation directory with new ones.
To resolve this issue, we recommend the following troubleshooting steps:
Reboot the Webgility machine.
Create a new installation directory and rename the old one.
Download the latest version of Webgility from portal.webgility.com
Disable any antivirus or firewall software temporarily during the installation process.
Right-click on the installation file and select "Run as Administrator.
Follow the on-screen instructions to install the latest version of Webgility (Help article).
Also, make sure that your primary machine and addon machines are both using the same Webgility versions, if any machine is running an old version then please install the latest version on that machine.
By following these steps, you will be able to install the latest version of Webgility without encountering the "double value" error message. If you continue to experience issues, please contact our support team for further assistance.
